Just how much financial trouble was the McDonnell family in? As their federal corruption trial continues it appears it depends on who you ask.

Tuesday it was the former governor sister- who like his wife- is also named Maureen. She is Bob McDonnell's real estate partner. The "Mo" in MoBo". She argued that taking the loans from Jonnie Williams was a business decision not an act of desperation.

Maureen Carney McDonnell describes her brother- the former governor- as a mentor and her best friend.

"I'm glad to be here in support of my brother today," Ms. McDonnell said leaving court. "Thank you all."

Together they bought two beach properties in Sanbridge, an investment she called her idea. They created an LLC they called "MoBo". Despite the beach real estate market falling apart, Ms. McDonnell said she was never worried about the money they might be losing.

"MoBo was something I never lost a night sleep worrying about," she testified.

Prosecutor Jessica Aber pushed Ms. McDonnell on a series of late fees and the frustration that she expressed in emails about the properties. At one point Ms. McDonnell wrote that wanted to:

"Sell the properties to relieve some financial pressure."

Ms. McDonnell blamed the late fees on her ex-husband who she claimed was stealing from MoBo- but overall she was insistent that she herself had plenty of money. The Williams loans, she said, made financial sense.

Aber was skeptical of that point. She asked "Was Williams giving a loan to an entity that was losing money and had no assets?"

Implying that the loan was in exchange for something greater.

An implication about her brother Maureen McDonnell strongly rejects.

"He's an incredible man," she said. "I am glad to be here to support him today."
